Application lefl September 10, 1919.

1o all fte/tom t may concern lle it .known that l, rl'rronas F. Seemann, a citizen or the United tates, residing at lllarsaiv, in the countyr olf losciuslio and tit-ate of lndiana, have invented a new and useiul lotary Valve, ot' which the following is a speciiication.

This invention relates to valves and it is the principal object oit the invention to provide a valve construction of the rotary type having ethcient means 'for cooling the valve, to prevent the heating of the valve, thereby insuring against sticking of the contacting valve members, due to expansion thereof, caused by excessive ilriction.

il still further object of the invention is to provide removable sleeve members, whi ch may be readily moved and replaced in the event that the same become Worn or otherwise rendered inoperative.

lilith the foregoing and other objects in viciv which will appear as the description proceeds, the invention resides in the combination and arrangement oi' parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment oi the inv' ition herein disclosed, may be made Within the scope oit what is claimed Without departing from the spirit of the invention.

through the rotary valve forming the sub- 'ject matter of the present invention.

rlhe rotary valve includes the circular' casing 7, which comprises. the outer Wall S, and inner Wall 9, the same being spaced apart to provide a cooling surface. The inner Wall 9, is provided with a cut-out portion l adapted to r vceive a quantity of gas passing through the valve.

Disposed Within the inner Wall lfadjacent the upper end thereof, is the key slot l2, which slot registers with a hey slot i3, formed in the sleeve member lat, to receive the key l5, which key connects the sleeve member lvl, to receive the inner Wall 9 of the casing, to prevent rotary movement, ofrthe sleeve la, with relation to the casing, when the valve is being operated.

El sleeve member lo, is positioned Within the sleeve member il and conforms with the shape thereof, to provide a close lit thereJ` between, to insure against the charge leaking at this point.

This sleeve member 1G, as clearly shown by the detail vieiv of Fig. of the drawings, is provided With a plurality of cutout portions 17, disposed adjacent the upper edge thereotl to permit a passage of Water, which is employed in connection with the valve, as a cooling medium to pass therethrough.

is shown, the sleeve le, is provided with lateral discharge openings 14 and l5 having communication with the cylinder inlet pipes and 6, leading to the engine cylinders. The sleeve i6, keyed to the valve proper is also provided ivith lateral open ings i6 and 17, which openings are adapted to register with the openings 14; and l5 of the sleeve la durino' the rotation of the valve, :for distributing a charge to the cyl inders of the engine.

he valve proper, includesl a hollow cone shaped member i8, having a central passage- Way 19, and an upper passageway 20, the central passageway having communication with the intake pipe 2l, leading from a carbureter, or similar charge forming device, While the upper passageway 20, has communication with the pipe 22, Which has connection with a suitable Water supply not shown.

This passageway 20, has communication with the chamber 23 formed at the base of the valve, through the vertical passageway Qfl and as shown, said chamber 23, has communication with a discharge pipe 25,

through Vwhich the fluid passes, after the same has accomplished the cooling result,

in its passage through the passageways 29 and 24,.

The valve proper is so constructed that the passageway 24 will move to a position to close the intake ports of the engine cylinders associated with the valve, while the cylinders are being fired, and to this end the passageway at 24 admits the cooling lmedium, to contact directly with the valve at its hottest point.

supportingdisk 26, forms the base for the valve and` provides means for supporting theV same in suitable relation with the engine cylinder, used in connection therewith. The supporting disk, is provided Vwith a central opening 27, which opening is in alinement with a depressed portion 28, 'formed in the lower end of the valve member 18, and receives the upper end of the operating shaft 29, which has its lower end suitably connected with an operating mechanism, not shown, whereby rotary moven ent oi the shalt 29, imparts a rotary movement to the valve 18,'or bringing the discharge port 34, thereof into alinement with the intake pipes 5 and 6, leading to the engine cylinders.

Supported on the upper end of the valve 18, is a disk 33, vwhich disk is provided with a central opening 34, to provide communication between the central passageway 19, and the intake pipeV 21, whereby fuel ,from the intake pipe 2l, is admitted tothe central passageway 19 of the valve.

An opening 85, is formed through the `disk 33, and provides communication be- 'lying within openings 39, Jformed in the lower surface oi the disk 37, whereby the disk 33 is prevented `trom rotary movement, whenthe valve member 1S is operated lt might be further stated that a coil .spring 48, surrounds cachot thesepins-39,

tor yexerting pressure onf the disk 33, thereby holding the disk into close engagement with the upper end of the valve member 18.

The valve 1S, is provided with a keyhole yslot 4l, registering with the key hole slot 42,

formed in the sleeve 16, whereby movement i ,scacco ot the valve member 18, is transmitted to the sleeve member 16.

lt it becomes necessary to replace one oi the sleeve members, due to the same becoming worn or otherwise rendered inoperative, it is only necessary to remove the cover 37, which is secured to the member of the valve, by means of the bolts 4:3, whereupon the disk 33, may be removed, thereby giving access to the key members which secure the sleeve members to their respective supporting elements.

lt will thus be seen in operation, the valve member 18, receives a charge through the intake pipe 2l, and distributes the same to the various cylinders ot the engine, due to the fact that the valve 18, is rotated, to bring the exhaust port thereof, into registry with the intake pipes 31 and 32 leading to the engine cylinders.

1Water, or other cooling iiuid, enters the chamber 30, through the pipe22, whereupon the same passes through the valve, and out through the discharge pipe 25, the flow of water being controlled by suitable pump mechanisms, not shown.

Having thus described the invention, what is claimed is 1. ln a rotary valve, a casing, a sleeve positioned within the easing, a valve member positioned within the casing, a sleeve keyed to'said valve member and contacting with the first mentioned sleeve, said va ve member and sleeves having ports adapted to register, passageways formed within the valve member adjacent to one of said sleeves, a stationary cover for said valve member, means extending into one ofl the passageways and through the cover for supplying a cooling medium to the valve, and means for supplying :fuel to the valve member.v

2. ln a rotary valve, a casing, a sleeve positioned within the casing and keyed thereto, a valve member within the casing and having a sleeve keyed thereto, said sleeves contacting to provide a leak-proof connection, said valve member having a lateral opening, said sleeves having openings registering with the opening in the valve member to permit the passage of fuel therethrough, a circular cover for the valve member, means for normally forcing the cover into engagement with the upper edge of the valve member, and a pipe extending through the cover for supplying a cooling fluid to the valve member and sleeves.

In testimony that l claim the foregoing as my own, I have hereto atlixed my signature in the presenceot two witnesses.

THOMAS F. SCOLLARD.
